Overview

Free browser-based image converter and editor

The Image Converter on sourcecodestack lets you convert, resize, crop, rotate, and fine-tune images right inside your browser — no account, no installation, and no data ever sent to a server. Drop in PNG, JPG, WEBP, GIF, AVIF, or PDF files, choose your output format, set a target resolution, and download the results immediately.

A built-in per-image editor goes further than simple conversion. Open any image with the edit icon to access four tabs — Adjust, Transform, Crop, and Metadata — each backed by a full undo/redo history. Make your changes in preview mode and only commit them when you click Apply, so experimenting is always risk-free. The batch system lets you add more images to an existing session without losing files or settings you have already prepared.

Frequently asked questions

Are my images ever uploaded to a server?
No. Every operation — format conversion, resizing, color adjustment, cropping, and EXIF stripping — runs entirely inside your browser using the HTML Canvas API. Your images never leave your device.
How do I convert a batch of images to the same format?
Upload all your images at once (or use the '+ Add More Images' button to append to an existing batch), tick the 'Apply settings to all images' checkbox, then select your target format. Every card updates simultaneously. Click download or use bulk export when ready.
Can I strip location and camera data from photos?
Yes. When you open the built-in editor and click Apply, the image is re-encoded through an HTML canvas which inherently strips EXIF, GPS coordinates, and camera information. The 'Strip EXIF' toggle in the Metadata tab is enabled by default.
What happens to images I have already edited if I add more files?
They are preserved exactly as-is. The '+ Add More Images' button appends new files to the current batch without touching existing cards, settings, or applied edits. Only clicking the main upload zone replaces the entire batch.
